Maximum pending asynchronous I/O for a file This is the maximum I/O operations the DS-Client will queue for each file from this backup set. | |
Use DS-Client’s settings | (Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: MaxPendingIOPerFile. |
Use specific value | You can override the default and set a custom value that only applies for this backup set. • This option is intended for high performance backup environments. You must be able to test the different settings to determine the optimal value. • This is only useful if the target storage containing the backup data is fast and efficient enough to take advantage of the increased I/O. • WARNING: Slower storage can suffer performance drops if this value is increased too much. |
Read buffer size for backup This option adjusts the internal buffer amount that the DS-Client allocates for reading individual files for backup. | |
Use DS-Client’s settings | (Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: FileReadBufferSize. |
Use specific buffer size (KB) | You can override the default and set a custom value that only applies for this backup set. • You must be able to test the different settings to determine the optimal value. • WARNING: Slower storage can suffer performance drops if this value is not properly set. |
